$ • Difters in being somewhat thinner, antennae rather sliorter 

 and thinner, and abdomen nonfoveate. 



JIab. — W. Australia: Bridgetown and Donnybrook — in nests 

 of Ponera lutta (A. M. Lea). 



Of rather more slender build than formicinus and with 

 ventral impressions different. In the male of fnrmicinun the 

 second segment is shallowly foveate in the middle of the apex, 

 and the third feebly impressed in the middle, the impression 

 shallower than on the second. In the present species the im- 

 pression on the second is wider and shallower, whilst that on 

 the third is decidedly deeper than that on the second, from, 

 some directions appearing as a round deep fovea. From the 

 sides the basal joint of the antennae appears to be fully twice 

 as long as the second, but from above the second appears to be 

 about two-thirds its length. 



Tmesijihorus curvipes, n.sp. 



(?- Of a rather bright reddish-castianeous, tarsi and palpi 

 somev>fhat paler. Clothed with short depressed and rather sparse 

 pubescence, but with a suudl fascicle on each side of under sur- 

 face of head behind each eye. 



Head with dense, strong punctures ; with two deep and fairly 

 large foveae between eyes, with a feeble basal impression. 

 Antennae fairly stout, almost extending to hind coxae, first 

 joint cylindrical, about as long as three following combined, 

 second slightly stouter, but no longer than third, third slightly 

 longer than fourth, fourth to eighth short and subequal, ninth 

 about twice as long, and twice as ,wide as eighth, and slightly 

 narrower but no shorter than tenth, the two combined slightly 

 longer than eleventh, wdiich is irregularly ovate. Profhor-ax 

 slightly longer than wide, sides somewhat angularly dilated at 

 apical third, thence strongly diminishing in width to apex, and 

 feebly to base, with a small sub-basal suboblong fovea, and a 

 larger irregular one on each side near base ; punctures as on 

 head. Elytra distinctly wider than long, much shorter than 

 abdomen ; punctures sparser than on prothorax but clearly de- 

 fined ; each with a distinct sutural stria, and a strong im- 

 pression between suture and shoulder. Ahdomtn with a narrow
